Abstract

The invention relates to the technical field of image processing, and specifically relates to a lung malignant tumor MRI identification method utilizing a maximum class separation distance method of a genetic algorithm. For the lung malignant tumor MRI identification method, a non-linear genetic array optimization model is added, and optimization of segmented images can be performed through the non-linear genetic array optimization model. Therefore, the segmented images obtained through the method are high in accuracy so that the identification of lung tumour is higher in accuracy.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an MRI identification method for lung malignant tumors using the maximum inter-class distance method introduced with a genetic algorithm. Background technique [0002] Medical image segmentation is an indispensable means of extracting quantitative information of special tissues in images, and it is also a prerequisite for 3D reconstruction and visualization of images. Segmented images are widely used in various occasions, such as location and diagnosis of diseased tissues, learning of anatomical structures, computer-guided surgery and 3D visualization, etc. [0003] MRI (magnetic resonance imaging) images are one of the important components of medical images, but because MRI images have a certain degree of noise, we need to preprocess the original MRI images in order to obtain better image quality and improve processing accuracy , to obtain the ideal segmentation effect...
